Video card GeForce gt 430 not working anymore

Hi everybody!
I have a big problem, I've just moved to a house and kept some time my pc downstairs so it went full of dust. So today I cleaned up all of my components including and specially the video card ( GeForce GT 430 ) , I removed it and vacuum it .
So I did put all together and tried to turn it off with a hdmi cable and a TV ( Sony ) - I didn't received any signal, so I brought my monitor ( Samsung SyncMaster913N ) and also black screen.
I have to mention that I did used it like 1 month before and it had worked.
If you could please save my day with any advices :(
Thank you !
 
Up - I tried with 3 different graphic cards and I still got a black screen , also this is a photo with the components

The motherboard has probably given up, maybe from static discharge. Vacuum's can produce static...
